    • A Neutral-Point Diode-Clamped Converter with Inherent Voltage-Boosting for a Four-Phase SRM Drive 

      Abdel-Aziz, A. A.; Ahmed, K. H.; Wang, S.; Massoud, Ahmed; Williams, B.W. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      This article proposes a new asymmetric neutral-point diode-clamped (NPC) multilevel converter for a four-phase switched reluctance motor drive. The inbuilt NPC clamping capacitors are used for both voltage level clamping ...

    • A Novel Converter Station Structure for Improving Multiterminal HVDC System Resiliency Against AC and DC Faults 

      Wang, S.; Ahmed, K.H.; Adam, G.P.; Massoud, Ahmed; Williams, B. W. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      In an effort to minimize the power disruption between a dc grid and ac grids that host power converters during ac and dc network faults, this paper proposes a novel converter station structure to improve ac and dc fault ...

    • A T-Type Modular Multilevel Converter 

      Wang, S.; Massoud, Ahmed; Williams, B.W. ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)
      This article proposes a novel modular multilevel converter (MMC) named 'T-type MMC' (T-MMC) for reliable, controllable, and efficient performance in energy conversion applications. Circuitry configurations and control ...

    • Analysis and Assessment of Modular Multilevel Converter Internal Control Schemes 

      Wang, S.; Adam, G.P.; Massoud, Ahmed; Holliday, D.; Williams, B. W. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      Adoption of distributed submodule (SM) capacitors in a modular multilevel converter (MMC) necessitates complex controllers to ensure the stability of its internal dynamics. This paper presents comprehensive analysis and ...

    • Strategies for Decoupling Internal and External Dynamics Resulting from Inter-Arm Passive Component Tolerances in HVDC-MMC 

      Wang S.; Adam G.; Massoud A.; Holliday D.; Williams B. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)
      Modular Multilevel Converter (MMC) performance may be adversely affected by passive component tolerances, such as submodule capacitance and arm inductance variations. Depending on control strategies, the differences in ...
